The slide begins on the 70th floor of the 1,018-foot U.S. Bank Tower in L.A., currently the tallest building in the United States west of the Mississippi. Riders of the slide must board a gray mat in order to properly slide down to the 69th floor, where the slide ends.

The slide was part of a project to attract visitors to the building. In addition to the slide, the 70th floor, called the Skyspace, has an observation deck that overlooks L.A. Visitors have to transfer elevators at the 54th floor to get to Skyspace.

Lucy Rumantir, the president and CEO of the OUE for the Americas, a Singapore-based company that owns the building, told the Los Angeles Times that the 1 1/4-inch thick glass slide is strong enough to hold a school bus full of people.

Many journalists have already taken the plunge. Los Angeles Times' Jessica Roy filmed her voyage down the Skyslide.
